chsh - change your login shell
chsh [ -s shell ] [ -l ] [ -u ] [ -v ] [ username ]
chsh is used to change your login shell. If a shell is not given on the command line, chsh prompts for one.
VALID SHELLS
chsh will accept the full pathname of any executable file on the system.
However, it will issue a warning if the shell is not listed in
the /etc/shells file. On the other hand, it can also be configured
such that it will only accept shells listed in this file, unless you
are root.
-s, --shell
Specify your login shell.
